    Ok, cors should be enabled in my google bucket now! Matt got his working, and told me how to do it in mine. Looks like the Range thing was needed, and then options seemed to work? Unless trying it out directly in cog-explorer isn't a full test... I don't think I have a cors plugin installed.

    Hi @cholmes
    Sorry, I'm already home (its 9:30 here).
    Its great to hear you managed to get it to run, good job!
    I inspected the SanFranciscoS2BGRN.tif case. Theres two things: 1) The default contrast correction is way off as the image seems to be in a good contrast already by itself. I'm working on this issue (as it currently affects all RGB images). 2) if this image originates from Sentinel 2, then bands are a bit odd. In the gdalinfo it displays the band description as B2, B3, B4, B5 (which is actually Blue, Green, Red and Near Infrared) so the colors are quite odd indeed.
    The second image has the same contrast issue. If you click on the wrench in the upper right and delete the 'sigmoidal' step, then the image should be quite normal. The default settings originate from a version where we thought only Landsat 8 images will be displayed.

    Forgot to reply here, but thanks! Things seem to be working really now. I'm definitely going to talk this up a lot at foss4g-na, and I think a lot of people are going to be blown away.
    Also I think will aim to do a medium post that features it some. Also need to announce my cog-map + tiles.rdnt.io service we're standing up (marblecutter lambda tiler for cogs).

    yes, joe added the cors headers for l8

    oh awesome! I'll tweet that out...
    and include it in a blog post soon.
    Google Earth Engine is able to create COG's now - composited a bunch of planet scenes, clipped to land.
    cog-explorer actually did better on transparency than qgis and marblecutter...

    nice

    Regarding the transparency: we cheat :D
    Chris Holmes
    @cholmes
    lol

    @constantinius
    We use black as transparent, this is why we see the fuzzy edges on JPEG images
    Chris Holmes
    @cholmes
    ah, gotcha. Well, whatever works - I'm never one to oppose cheating in technology :)

    Hi @cholmes! How's the conference? I've heard there was a COG BoF session? Any news?
    Chris Holmes
    @cholmes
    Hey @constantinius ! It's good. Cog BoF was quite good. Drew took some notes - https://cryptpad.fr/code/#/1/edit/5JKq9WUUR9DH607TR9zx7Q/8v6DcTnYmOdvB-D7wXwH0lr1/
    I need to check them over and add to them and I'll put a blog post on it.

    @constantinius
    Ah, great, I'll have a look!

    But I think we'll likely put the 'spec' on github, maybe make a little cog / cogeo github org, to put the website and the spec.
    But there was quite a bit of interest, 20+ people showed up.

    @constantinius

    Wow, sounds like its getting traction!

    But I think we'll likely put the 'spec' on github, maybe make a little cog / cogeo github org, to put the website and the spec.

    Sounds reasonable!

    Yeah, lots of enthusiasm here. And RasterFoundry just implemented COG importing, which works great as well.

    This is awesome. Especially considering the age of TIFF itself.
    We are working on a geotiff.js release here (will be 1.0.0-beta). I hope I'll finish it before your talk (tomorrow, is it?)
    Chris Holmes
    @cholmes
    Awesome! Yup, talk is tomorrow, at 9am St. Louis time.

    Hello, I'm trying to use this library on my angular application, but I'm getting lot of errors, does someone be able to integrate it?
